1 I Be it known that I,' CARLADAMS, a subject of the Emperor-of, Germany, and'a resident, :of Easton; county of Northamptorgn; State of. Pennsylyanim have invented certain new and useful Improvements in Warp Stop-Motions'for Looms, of which the following a specification. I

its object 'to provide such machines with an alarm whichi ifg drawing, in which Figure 1 illustrates myinvention in cross I section takenon the'line v,1 -1 of Fig. 2; Fig.

2 is a partial .Iplan viewfand Fig. 3 is'ga horl "zontal section on the line'3- 3 of Fig. '1.

i I A'represents. a frame secn'redrat both ends to a-stationary' portionflB ofy-the loom as shown at C. This frame runs crosswiseof the'loom so that the usuelwarpithre'ads D run at 'suh stantially right an lea-thereto.- i
